This April 2021 report from Schneider Electric’s Buildings Research Center emphasizes three layers which the authors contend need to be understood in the context of “open” building management systems.  These include (1) Data acquisition/sharing, (2) System integration, and (3) Building orchestration. The report proposes a framework, clarifies terminology, and outlines key criteria associated with being “open” — including how these criteria influence the complexity and performance of the BMS. Example use cases for each are presented.
